STOVE-TOP.

Specification of Letters Patent.

Patented Aug. 11, 1908.

To all whom it may concern:

Be it known that I, CHARLES M. GENTE- NER, citizen of the United States, residing at Aurora, in the county of Kane and Stateof Illinois, have invented certain new and useful Improvements in Stove-Tops, of which the following is a specification.

My invention relates to stovesand especially to heating stoves, having particular reference to the construction of the top plate and attachments.

The ordinary form of plate is furnished with a central opening provided with a sepa.

rate closure or lid, and having a cover pivotally hinged to the top plate, said cover being ornamental to correspond with the general design of the stove and forming a finish for the top.

The chief objects of the improvements which form the subject matter of this application are to provide a convenient lid or door for the feed opening that can be readily opened to permit of the introduction of the fuel, that will retain its open position, and that can be operated either with the hand or any ordinary stove utensil.

Further objects of my improved stove top are to provide a deflector or chute to guide the coal from the hod into and through the feed opening; to construct this chute so that it will be entirely out of sight beneath the top plate except when in use, and to furnish a mechanism coacting with the feed door to shift said chute to its operative position external to the stove casing, such shifting both into and out of operative position being automatically controlled by the opening and closing of the feed door.

Other objects are to supply a vent opening.

auxiliary to the feed aperture; to furnish said vent opening with a damper which is automatically operated by the shifting of the stove top or cover; and to provide means for sliding said damper independently of the action of said cover.

I accomplish the above objects by the employment of a top plate and attachments constructed in the manner illustrated in the accompanying drawing which formsa part of this application, and in which Figure 1 is a top plan view of a stove top plate embodying my improvements; Fig. 2 is the plate with attachments removed g Figs. 4; and 5 are top and edge views, respectively, of the damper.; Fig. 6 is a top plan view of the chute; Fig. 7 is a bottom plan'view of a fragment of the cover; Fig. 8 is a fragment of the top plate showing a lateral margin of the feed opening, viewed from the inside 5 Fig. 9 is a bottom plan view of the feed door; Fig. 10 is a fragment of the feed door showing the hinge construction, and Fig. 11 is a rear elevation of the cover.

Referring to the details of the drawings the reference numeral 12 indicates the top plate of a stove, which is shown circular in outline although the shape may conform to any style of stove. The general contour of the plate is convex u on the upper surface adjacent the margin, sifightly modified in the brear by the pipe opening 13, and presenting a horizontal face 14 in the center, which is covered normally by a cover 15 pivoted in the usual manner by a lug 16 engaging a hole in the plate. This cover is of 'the ordinary construction, conforming in ornamental design to the general pattern. The rear margin of the cover is cut away at 17 and the line of section partly filled in by a web or wall 18 leaving an opening 19. An approximately quadrangular section of the plate is cut away in front to form a feed opening 2O which does not extend quite through the margin but leaves a connecting curved bridge 21. The opening 20 is provided with a lid, or trap door 22, which corresponds in form to the general shape of the top plate and when closed forms a continuation of said plate. This door lies horizontally when closed as shown in full lines in Fig. 2, and stands vertically when open, as shown in dotted lines in the same ligure. When closed the front margin rests upon the bridge 21, and the lateral margins overlap the plate, engaging surfaces 23 fitted to make a good joint, the rear margin rests upon a ledge 24, formed with the top plate 12,. The rear corners of said cover are supplied with integrally formed hook-shaped lugs or hinges 25, and these hooks are received in notches 26 in the side of the feed opening, and the points 27 of said hooks engage lugs 28, formed in the top plate, when said door is in extended or open position, and act as stops to hold the a vertical section; Fig. 3 is a top plan view of l, door upright. This construction' permits the door together with its attachment now to be described, to be readily removed, which is doneby tilting the door forward a few degrees from its vertical position, or until the hooks 25 are released from the lugs 28, when the structure may be lifted bodily from its seat. Directly beneath the door 22 when in closed position is located a fuel chute which is composed of a deflecting plate 29, curved to fit the inner margin of the bridge 21, against which it rests, and provided with rearwardly extending side wings 30 which flare outwardly from below upwards and are pivotally attached by bolts 31, to arms 32 formed integral with the door 22. l/Vhen said door is opened the action of the arms 32 is to extend the chute forwardly and upwardly, upon the bridge 21, and project the plate 29 and wings 30 above the feed opening, as shown in dotted lines in Fig. 2. Upon the horizontal ortion 14 of the door 22 are aseries of sma l vent holes 33 which may be arranged in ornamental curved lines as shown in Figs, l and 9. To aid in raising the lid or door 22 its front edge is furnished with a lip 34, in which is a hole 35, which may be engaged by a hook or rod .in case the lid is too hot to handle.

Between the feed opening 20 and the pipe hole 13 is located a depression or recess 36 having in its center a still further depression 37 provided with a vent opening 38. end margin of the depression 36 is cut away at 39 to form a channel for the passage of a reduced portion or handle 40 of a slide plate or damper 41, which is a thin plate just Hush with the surrounding surface 14. The handle 40 is provided with an elongated recess 42 to receive the head of a retaining `pin 43 the body of which passes through a slot 44 in the bottom of said'recess. The outer end of the handle has a down-turned lip 45 by which it can be grasped to operate the damper. The latter is supplied with an aperture 46 which corresponds with the vent opening 38. Upon one side of the handle is a vertical fiange 47 furnished with a notch 43.

The partial wall or web 13 previously described is wider upon one side of the opening 19 and this projection 49 is adapted to engage said notch 43 when the cover 15 is swung outwardly, and the inclination of the said wall 18 and its projection 49 is adapted to propel the slide or damper in the direction in which the cover is moving. When the cover 15 is in its initial position concentric with the stove plate 12, the projection 49 is out of engagement with the notch 48, and the slide or'damper41 is free to move independently of said cover and may then be operated by the lip 45 upon its extremity, a notch 50 in the lower margin of the cover 15 giving passage to the flange 47.

By this arrangement the damper, if open, is automatically closed whenever the cover is swung off from its seat upon the plate 12 and since the said cover acts as a lock for the trap door 22 and must be swung off from its seat, before the trap door can be raised, it-

follows that the vent opening 38 will always be closed whenever the feed door is open, and this cooperation is necessary since the gases would escape through the damper opening 38 if both apertures are open at the same time.

To supply the stove with fuel, when all parts are in their initial ositions, two procedures are necessary, 'rst to swing the cover 15 off from its seat and then release the trap door at the same time closing the damper and second, to raise the feed door which elevates the chute to operative position. The reverse of these movements will restore the parts to initial position with both vent openings closed.

Having thus described my invention what I claim as new is 1. A stove top having a smoke flue and a fuel opening therein, a feed-chute pivotally mounted within said top and below said fuel opening, a door for said fuel opening, said door and feed-chute having inter-engaging portions whereby the latter will be raised and lowered by the opening and closing of the door and a cover arranged to control the operation of said door.

2. A stove top having a smoke-flue, a vent and a fuel-opening, a damper slidably mounted over said vent, a cover pivotally mounted over said damper, means connecting said damper and cover, whereby the movement of the latter on its pivot will slide the damper, and a removable door for said fuel-o ening.

3. stove-top having a smoke-flue, a vent and a fuel-opening, a damper slidably mounted over said vent, a hinged door for said opening, and a cover arranged over said damper and extending partially over said door and controlling its operation, and means whereby the movements of the cover will automatically operate the damper.

4. The combination with a top plate provided with a fuel opening and a vent, a door for said fuel opening, a fuel chute pivoted to said door, a cover adapted to lock said door in closed position, a damper for said vent,

and means for operating said damper by the cover.

5. A stove-top having a smoke flue, a vent and a fuel opening, a damper slidably mounted over said vent, a chute pivotally mounted within said top and adapted to be projected upwardly through the fuel opening, a door for said opening said door adapted to operate said chute, a pivoted cover ar- Cil seams a ranged to control the operation of said door in the manner described, and means connecting said cover and damper whereby the operation of the cover will automatically operate the damper.

6. In a stove top having a fuel opening7 a opening of said closure and damper.
